Joomla 3.7.4 VM 3.2.2 PHP 3.6.31

Hi folks. Since August 9th my Paypal IPN has stopped working (it's been working for 5 years). Here's the error log:

Error log:

It seems that it's also affecting other components that use IPN. According to my hosting, other users are also being affected, not just me. It would seem that Paypal started to introduce changes in June and that these may now be causing the problem. My host supports SSL, HTTP 1.1, TLS 1.2 and SHA-256 so complies with all Paypal's security requirements.

I'm really struggling to work out what's going on here. Could my Paypal payment plugin somehow be out of date?

Yes, mine stopped working Aug 9th as well. Don't want to hijack this thread - just want to show this isn't an isolated incident (and I'm only on J2.5.27, VM2.6.12.2, PHP5.6.31).
